Procedure

A solution of maleic anhydride (9.8g-0.1 mol) and 1-hexene (8.4g-0.1 mole) in propylene glycol methyl ether acetate (30g) was heated under agitation and nitrogen to 60 deg. C. A solution of 2.5 g of 75 wt % t-butyl peroxyneodecanoate in 6 g of propylene glycol methyl ether acetate was then injected into the reaction vessel within half hour via a syringe pump. The reactants were agitated for another hours at 60° C. before being cooled to room temperature. The product was the poured into methanol which caused precipitation of a white solid which was filtered and air dried to give 10.5 g of a maleic anhydride/1-hexene copolymer. Hydrolysis was carried out by.
